So, I've been doing the typical research on this subject and still currently nobody makes a replacement set of rubber body mounts/ bushings as all the GM ones are out of production.
I've searched all the usual forums, Layitlow, Impalassforum, here etc. and it appears some have mentioned the Energy Suspension Kit 3.4145 Poly Kit for the 1991-1996 Caprice/ Impala would work on the 80's Caprice models. I haven't seen anyone come back and say they don't work. I would be using the Black (Graphite) versions of the poly ES kit. There is also talk about utilizing and ordering the remaining bottom cushions that were not installed from the factory. I got under the car quickly last night and it appears only GM Position #1 is missing the lower mount, as well as GM Position #5, but that is an upper mount only and just sits between the frame and the body. That is my 1987 Caprice Coupe as reference.
Has anyone here actually successfully used the above mentioned kit? The ES kit utilizes the factory sleeves and a combination of ES and Factory washers. There is a bolt and washer hardware kit on Summit for body mounts, but still would require to utilize the stock sleeves.
What are your thoughts?
